To provide an inexpensive fuel-supply equipment of an internal combustion engine by which startability is improved, and HC can be reduced.
A fuel-injection valve 8 is installed in a position where the center of injection direction does not intersect the center axis of an intake path 1, and in a manner that injected fuel swirls around the axis of the intake path without aiming the injection direction straightly at an intake valve 11. The fuel-supply equipment is constituted so as to swirl the injected fuel at least at the part where a heater 13 is installed. The heater 13 is installed all over in the peripheral direction of the intake path 1, and the cross-sectional area of the path in the part of the heater 13 is made larger than the cross-sectional area of the intake path 1.
